The management server 6 has a function for accumulatingpersonal information and position information and a function 10 for transferring those information to the concentrated monitoring board 7. The management server 6 also has a function for relaying and transferring a signal from the concentratedmonitoring board 7 to the content server 4.

FIG. 2 is a flowchart showing exchange of signal in respective portions of the system shown in FIG. 1. A person who uses the emergency notification system is required to purchase the cellular telephone terminal with a position measuringfunction. The purchased cellular telephone terminal 1 can receive service of the emergency notification system by registration. Registration is required at once unless data is modified.

Flow of registering operation will be discussed with reference to FIG. 2. Person who desires to make registration, at first establishes connection with WAP server 10 from the cellular telephone terminal 1 (step S1) to open a menu screen A1. Themenu screen image A1 is a main or united menu of services provided by the mobile communication network 2 and includes an item of emergency notification service in addition to weather report, news and so forth. When the item of emergency notificationservice is selected among the items in the menu screen A1, an emergency notification service menu screen image A2 is displayed (step S2). This screen image is a screen information transmitted from the WAP server 10 or the content server 4 and isconstructed as a menu for selection of "fire dispatch/ambulance/registration". It should be noted that the emergency notification service menu screen image A2 may be stored in a storage device of the cellular telephone terminal as image information. Ifthe image information of the emergency notification service menu screen image A2 once are stored in the storage device of the cellular telephone terminal, the emergency notification service menu screen image A2 can be opened without requiringtransmission from the WAP server 10 and the content server 4. On the other hand, by shipping the cellular telephone terminal in a condition preliminarily storing the content of the emergency notification service menu screen image A2 in the storagedevice thereof, this screen image can be recalled without establishing connection with the WAP server 10.

When "Registration" is selected from the menu in the emergency notification service menu screen image A2, registration operation is initiated between the cellular telephone terminal 1 and the sign-up server 3. Then, from the cellular telephoneterminal, an authentication demand for the emergency notification service, a Sub ID as ID information unique to the cellular telephone terminal 1 are transmitted to the sign-up server 3 (step S3). The sign-up server 3 transmits screen image informationnecessary for initial registration to the cellular telephone terminal 1 (step S4). When the screen image information is received, the cellular telephone terminal 1 displays a registration screen image A3. A person desiring registration inputs necessaryinformation, such as name, telephone number and so forth according to guidance on the screen image, to transmit to the sign-up server (step S5). The information transmitted to the sign-up server 3 is directly accumulated in the database 5. On the sideof the emergency notification device 9, since all of these series of operation is performed by the sign-up server 3, registration can be performed without requiring manual operation. After completion of the registration, the emergency notificationsystem can be available by the cellular telephone terminal.

Next, as an example, a case where the user desires to perform emergency notification relating to occurrence of fire to a fire station, will be discussed. At the occurrence of happening requiring emergency notice, the user establishes connectionwith the WAP server 10 from the cellular telephone terminal 1 (step S6). Then, the user opens the menu screen image A1. Among items in the menu screen image A1, the screen notification service menu screen image A2 is recalled (step S7). When "Fire" isselected among items in the emergency notification service menu screen image A2, a packet signal containing the emergency notification reception demand, Sub ID and emergency classification, is transmitted to the content server 4 (step S8). The contentserver 4 issues the authentication demand based on transmitted Sub ID with the sign-up server 3. When authentication is completed, an individual information is identified.

The content server 4 transmits a position measurement demand to the cellular telephone terminal 1 (step S10). In the cellular telephone terminal 1, a position measurement verification screen image A4 for selecting whether position measurement isaccept or not, is displayed. It should be noted that this screen image can be eliminated by setting. When "YES" is selected, position measurement of the user is initiated between the position measuring server 11 and the cellular telephone terminal 1(step S1). In practice, GPS is used. The position measuring server 11 transmits information designating satellite available to the cellular telephone terminal, to the cellular telephone terminal 1. Utilizing the satellite designated by the informationtransmitted from the position measuring server 11, the cellular telephone terminal 1 derives latitude and longitude of own position to transmit to the position measuring server 11 as temporary position information. In the information of latitude andlongitude, error can be contained. The position measuring server compares information transmitted from the cellular telephone terminal 1 on the basis of already known latitude and longitude of the own position and an orbit information of GPS forperforming correction. The position measuring server 11 transmits information containing corrected latitude and longitude and error to the cellular telephone terminal 1. By this information, the position of the cellular telephone terminal 1 can beidentified more accurately. The cellular telephone terminal 1 transmits the information containing latitude, longitude and error to the content server 4 (step S12).

The position information, personal information and information of emergency classification and so forth are transferred to the concentrated monitoring board 7 from the content server 4 (step S13), and displayed on a monitoring screen of theconcentrated monitoring board 7. When reception of emergency notification is confirmed, the concentrated monitoring board 7 returns a reception signal to the content server 4. Upon confirmation of the reception signal, the content server 4 transmits areception information to the cellar telephone terminal 1. The cellular telephone terminal 1 then notifies that the emergency notification is normally received, to the user by reception display A5 and vibration of the main body of the cellular telephoneterminal (step S14). On the other hand, on the basis of the information on the display screen of the concentrated monitoring board 7, an operator calls out associated offices, for example, fire engine, ambulance and so forth.

In the shown embodiment of the emergency notification system according to the present invention, man of impaired hearing can perform emergency notification identifying a position and kind of emergency notification using only normal cellulartelephone terminal without using a voice even when own position is not known at a visited place.

FIG. 5 shows an overall construction of a wide area emergency notification system as the fourth embodiment of the emergency notification system according to the present invention. Mobile communication networks 32 and 42 connected with each otherare respectively connected to emergency notification devices 39 and 49 for providing emergency notification services in respective service areas A and B, and for providing wide area service in both areas. These mobile communication networks 32 and 42provide wide area services in the service areas A and B, respectively. The emergency notification devices 39 and 49 are connected with each other by a dedicated line 58. The mobile communication networks 32 and 42 have the same construction andfunction as any one of the mobile telecommunication network 2 of the first to third embodiments set forth above. On the other hand, the emergency notification devices 39 and 49 may have the same construction and function as any one of the emergencynotification device 9 of the first to third embodiments set forth above. In FIG. 5, a part of internal construction of the emergency notification device is eliminated from illustration. Databases 36 and 46 store tables storing Sub ID and registeredarea in connection with the registrants registered in all of service areas. The service areas A and B may be separate areas, for example. However, it may be possible that the areas are set in partly overlapping manner.

The mobile communication networks 32 and 42 having different service areas are connected to a gateway 40. Using this gateway 40, the user of the mobile communication network 32 of the service area A may receive service in the mobilecommunication network 42 in the service area B. The users of the cellular telephone terminals 31 and 41 may communicate either in the service areas A and B. Namely, the user may use the cellular telephone terminal without considering, to which of themobile communication networks, the own terminal is communicating.

Discussion will be given for an example where user of the emergency notification system using the mobile communication network 32 of the service area A and registered in the emergency notification device 39, are present. The user using theemergency notification system in the mobile communication network 32 purchases the cellular telephone terminal 21 with position measuring function and makes initial registration. This initial registration is completed by receiving personal informationin the sign-up server 35 of the emergency notification device 39 connected to the mobile communication network 32 through the private network 38 and registering the personal information to the database 36. When the user desire to perform emergencynotification to a fire station in the service area A, similarly to the examples of the first to third embodiments, the emergency notification device 39 receives the emergency notification to take necessary action. The personal information of the user isstored in the database 36. Thus, personal information necessary for authentication or so forth is read out from the database 36.

It is assumed that the user in possession of the cellular telephone terminal 31 moves from the service area A to the service area B. While the service area A and the service area B are constructed with different mobile communication networks, theuser may use the normal cellular telephone terminal 31 through the mobile communication network 42 without requiring user's attention by operation of the gateway 40. When emergency notification is made using the cellular telephone terminal 31 from theservice area B, the authentication demand is transmitted to the sign-up server 45 through the mobile communication network 42. The sign-up server 45 makes reference to a relationship between the Sub ID and the registered area of the registrantregistered in all of service areas stored in the database, to recognize that the user in possession of the cellular telephone terminal 31 is registered in the service area A.

When recognition is made that the information of the user is registered in the service area A, the emergency notification device 49 inquires information of the user for the emergency notification device 39 in the service area A connected throughthe dedicated line 58. The information of the user using the cellular telephone 31 is copied from the personal information in the database 36 in the emergency notification device 39 of the service area A. The copied personal information is temporarilyaccumulated in the database 46. Then, on the basis of the copied personal information, authentication is performed. Then, the user may receive service similar to that can receive in the service area A where the user is registered, even in the servicearea B. In this period, the user does not pay any attention for difference of the service area and is not required any special operation.

Although the present invention has been illustrated and described with respect to exemplary embodiment thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omission and additions may be madetherein and thereto, without departing from the spirit and scope of the present invention. Therefore, the present invention should not be understood as limited to the specific embodiment set out above but to include all possible embodiments which can beembodied within a scope encompassed and equivalent thereof with respect to the feature set out in the appended claims.

For instance, the emergency notification system and the emergency notification device according to the present invention is not particularly applicable for calling fire engine and ambulance but can be applicable for emergency notification forother purpose. Furthermore, it is possible to transmit screen image information requiring information of degree of injury, presence or absence of external injury to the cellular telephone terminal for collecting more information.

As set forth above, the emergency notification system and emergency notification device can perform emergency notification using only normal cellular telephone terminal and without speaking in voice.
